Hi All,I’ve posted this on the yahoo 340R owners group without any luck. Perhaps you guys can offer some advice…??Ever since I’ve owned my 340R (just over a year now) it’s had an annoying engine rattle at around 2500rpm. This only seems to occur when the car’s warm and accelerating in lower gears, it disappears straight away once you’ve passed 2500rpm. I’ve tightened the rear diffuser, loose number plate holder rubbing on the exhaust and the anti tizz (?) exhaust bracket. It’s still there… It sounds as if it’s coming from the top of the engine, maybe throttle related?? Any ideas on what to tighten up or check gratefully received!Will340R #153
